Patent CA-2163971-A1 (CA)
Title: Process for determining and using the quantity of filling press material in solid-liquid separation with a filter press
Inventor: HARTMANN EDUARD
IPC: B30B9/02
Filed: 1995-03-21
Abstract: A determination of the amounts of fill of material (7) to be pressed in the solid-liquid separation by means of a filter piston press with a pressure element (6) for several successive pressing operations is made with the aid of a consideration in the yield/output diagram. Under a presupposition regarding the position of characteristic curves connecting various operating points in this diagram and by the interposition of an imaginary operating point it is possible to determine the changes in yield and output for each pressing operation and therefore the amounts of refill to be used in such a way that a maximal product of yield and output results for the solid-liquid separation operations when predetermining free process values.      The method provides an automatic adaptation of the fill time to the compressibility of the materials. By means of this it is made possible to feed in material (7) of very different compressibility automatically and without having to predetermine reference values in such a way that an optimal behavior is achieved in respect to the yield and the juice extraction behavior of a filter press.

Patent CA-2174404-A1 (CA)
Inventor: HOSHINO TATSUYUKI
IPC: F04B27/10
Filed: 1996-04-17
Abstract: A lubricating mechanism for a piston type compressor in a refrigeration system. A cam plate is mounted on a drive shaft for integral rotation therewith in a crank chamber, which is defined in a casing. Pistons are coupled to the cam plate and reciprocate in cylinder bores extending parallel to the drive shaft. Each piston compresses refrigerant gas containing lubricating oil mist and discharges the compressed refrigerant gas from the compressor during rotation of the cam plate. The refrigerant gas is supplied into the crank chamber and is circulated in the casing. The lubricating oil is supplied to various moving parts from a location near the drive shaft. An oil pan is provided outside and to the side of the casing for collecting lubricating oil. A recovering passage connects the oil pan with the crank chamber to convey the lubricating oil from the crank chamber to the oil pan for collection. A guide passage guides the lubricating oil collected in the oil pan to the location near the drive shaft using gravitational force.      By mounting the oil pan on the side of the casing, the oil pan collects relatively less liquefied refrigerant and more oil, and thus improves lubrication of the compressor.

Title: Front roller feeder
Inventor: ACKERMANN MANFRED
IPC: D05B27/10
Filed: 1996-05-24
Abstract: A fabric feed mechanism that includes a forward feed roller located forward of the stitch forming area and a rear feed roller located to the rear of the stitch forming area.  The drive to the forward and rear feed rollers is synchronized such that the fabric is fed to the stitch forming instruments in a relaxed and un-stretched condition.  There is a independently applied downward pressure to forward and rear feed rollers and the forward feed roller is raised along with the presser foot.   The front feed roller has  sections that are located on opposite sides of the presser foot toe to thus ensure that the top layer of fabric is fed under the presser foot rather than riding up the front roller.  A material folding device is located forward of the stitch forming area for folding material to be fed to the stitch forming area.  An adjustable edge guide member is mounted on the bracket for the forward feed roller such that the edge guide is adjacent to the forward feed roller when the forward feed roller is operative and swings forward toward the material folding device when the forward feed roller is raised where it functions as an edge guide for the material as it is being loaded into the folder and under  the  front  feed  roller.    A  differential  feed mechanism is provided below the front roller which can be adjusted to vary the forward feed velocity of the lower ply of material relative to the upper ply which allow the machine operator to align the cross seams such that they match and control the top and bottom ply such that they come out even.

Filed: 1996-02-09
Abstract: Biomolecule analysis using anodic oxidation of aqueous sodium 9, 10-diphenylanthracene-2-sulfonate (DPAS) and 1- and 2-thianthrenecarboxylic acid (1-THCOOH and 2-THCOOH) in the presence of tri-n- propylamine (TPrA) as a coreactant in aqueous solution produces electrogenerated chemiluminescence (ECL). In addition, the cathodic reduction of DPAS in the presence of peroxydisulfate (S2O82-) as a coreactant also produces ECL in an acetonitrile (MeCN)-water solution (1:1 by volume). The oxidation of chlorpromazine (CPZ) produces an ECL emission in the absence of an added coreactant following an unprecedented "self-annihilation" mechanism.
